This project will produce important information on the movements and migratory destinations of humpback whales from small, unrecovered populations off Rarotonga (Cook Islands) and New Caledonia.

Greenpeace is communicating this critical non-lethal scientific research to the wider public as part of their campaign against Japan's unnecessary lethal "research" in the Southern Ocean Whale Sanctuary.

On their journey, the humpbacks, like hundreds of thousands of other whales, face a range of threats including ship strikes, entanglement in fishing gear, pollution and the impacts of climate change.

Every year, more than 300,000 whales and dolphins die just caught in nets. The one place you might think they would be safe is a whale sanctuary like the Southern Ocean. Not so. Once in Antarctic waters they face the threat most easily ended - whaling.

The Southern Ocean Whale Sanctuary was meant to be a safe haven but every year the Fisheries Agency of Japan send a fleet of whaling ships to kill in the name of science. For the third year running they aim to hunt down almost 1,000 minke whales.

This year, they also plan to kill 50 threatened humpback whales and 50 endangered fin whales.

All of these whales will die for so-called 'scientific research' - but even the International Whaling Commission has labelled the "research" needless and urged the Japanese government to stop.

In reality, the "research" is commercial whaling in disguise - and the whale meat actually ends up in supermarket shelves in Japan, even though few people eat it anymore. Commercial whaling is banned under IWC rules.

In contrast, the Great Whale Trail project is contributing to real scientific efforts without killing whales.

When two of our activists were detained after exposing major corruption in the Japanese whaling industry -- we knew the Japanese authorities breached internationally guaranteed human rights. Now, as these two activists prepare to take the stand...
